To aZZ whom it may concern:

Be it known that I, MILTON M. ADLER, a citizen of the United States,residing at Newark, in the county of Essex and State provements inpyrotechnical devices; and

the invention has reference, more particularly, to an improveddetonating fire-work or fire-cracker. i

20 to provide a novel construction of detonat The invention has for itsprincipalobject ing fire-work r fire-cracker which is f safe to handle,which will not fly apart when set off so as to endanger the eyes orperson of theuser, or entail the risk of igniting fires,

- and which is constructed toproduce, when set off, a series orintermittent succession of detonations, rendering the same of pleasingand interesting effect, and providing a fire-work or fire-cracker whichwill operate for a comparatively long time after it is ignited. v

Other obj ects .of this invention, not at this time-more particularlyenumerated, will be clearly understood from the following de taileddescription of the same.

- ;With the various objects of this invention in view, the sameconsists, primarily, in the novel detonating fire-work or fire-crackerhereinafter set forth; and, the invention consists, furthermore, in thenovel arrangements and combinations of the severalfdevices and parts, aswell as in the; details of the. construction of the same, all of whichwillbe hereinafter more fully described in the. following specification,and'then finally a; embodied in the claims'appended hereto.

The invention is clearly illustrated in the accompanying drawings, inwhich Figurel is a perspective view of the complete fire-work orfire-cracker, made accordingito' and embodying the principles ofthepresent invention; Figure 2 is a longitudinal centralqsection throughthe same; Figure 3 is'a'jcross section. through the same,taken online 3-3 in said Figure 2; and :Figure of said fuse element 3.

isa plan View of a combustible carrier sheet upon which a plurality of;pastilles 7 o'r lozenges of pyroteclinical' composition are mounted, andwhich is adapted to be" enclosed in the outer case of the firework, saidView also showing the, attachment to said rsn'r QFFWE,

carrier sheet of an ignition fuse. a

Similar characters of reference are employed in all of the hereinabovedescribed views, toindicate corresponding parts.

Referrlng now to said drawings", the refence character 1 indicates acombustible car such astissue paper, upon which are caused to adhere aplurality of pa'stilles or lozenges 2' consisting of a pyrotechnicalcomposition adapted to produce detonations when ig nited. It will, ofcourse, be understood that thereare many different pyrotechnicalcom: 5

positions known tothose skillcdfin the art which, whenignited,willproduce detona-s 'r'ier sheetfpreferably made of, thin paper,

tio'ns, andconsequently, inthis respect I do not desireto limit myselfto, the use of any particular composition so characterized, al-

though l' prefer to employ a composition,

heretofore known and usedto produce intermittent detonations, and, whichcomprises amixture of gum-arabic, carbonate of magnesium, whitephosphorus, red ocher and potassium chlorate. The" pastilles or lozenges2 of pyrotechnical compo'sitionlare arranged in a group the members ofwhich are suitably spaced apart. It is preferable to treat the paper orother carrier sheet 1 with some chemical adapted to insure continuedcomic bustion thereof once the same is ignited. A chemicalsuch assaltpetermay beemployed for such purpose, although I do not wish to beunderstood as confining myself to the use of that substance for thepurpose indicated,

After thecarrierjsheet 1 with its pastilles or lozenges of pyrotechnicalcomposition applied thereto is prepared, a fuse element 3,

of a suitable easily combustible material, is

attached to the carrier sheet. One end of said'fuse element is attachedby a suitable adhesive to the carrier sheet, preferably (although notnecessarily) to the center of the sheet where the group of pastilles orlozenges 2 of, pyrotechnical' composition is mounted. After said fuseelement .3 is thus attached thereto, the carrier sheet is folded orcrumpledinto a roughly ball-like body from the interior of whichprojects the free end The reference characters indicates cyjlindrical ortubular 'casin open at its re; spective ends, and"prefera lyrn'ade'of'comparatively heavy paper orlight cardboardg The ball-likebody lIllQQ'flYhiCll";tl'l6. ;C ITiQIIf 6 sheet is formed (as aboveexplained) is ing 4, so thatthe same is positioned in terniediate theopen ends' of the latter, and
